Food addiction is characterized by impulsive decision-making, compulsive food intake, and a loss of behavioral control toward highly palatable foods. Impulsivity has been described as a predictive vulnerability marker for addiction disorders. The ventral hippocampus (vHPC) to prelimbic medial prefrontal cortex (PL mPFC) pathway has been associated with impulsive operant responses towards highly palatable foods and food-motivated behaviors. However, the electrophysiological dynamics between these brain areas underlying impulsivity are not well understood.In the food addiction animal model, mice were trained in operant boxes to develop a food-addictive-like behavior. Mice were tested for three addiction-like criteria and four vulnerability phenotypic traits, characterizing addicted and non-addicted mice. Stereotrodes were implanted in the mPFC and the vHPC. In vivo electrophysiological recordings were performed during operant sessions. Impulsivity was measured by the non-reinforced active responses during the time-out periods (15 s) after each pellet delivery. A detailed study of the impulsive response patterns was performed to determine the time windows of interest. Comparisons were made between local field potential (LFP) power and spiking activity locally in the prelimbic area (PL) of the mPFC and the vHPC. The vHPC-mPFC connectivity, directionality, and phase-amplitude coupling were also analyzed.Addicted mice showed increased impulsive-like behavior throughout the protocol, characterized by an increased ratio of lever pressing and a burst-like responding pattern.These findings reveal varied impulsivity features associated with distinct electrophysiological signatures, offering insights into novel mechanisms to better understand the brain pathways involved in the onset and development of food addiction.
